reactjs - Webpack : split and share vendor chunk across pages not working -

i configured webpack split vendor , app chunk. vendor chunk used across page. vendor file work app file built it. project has multiple page, each page built on own , have own app.js , bse.js. want use bse.js across pages.

page have:  - app.js  - bse.js page b have:  - app.js  - bse.js page c have:  - app.js  - bse.js 

i want use bse.js shared vendor chunk pages. browsers load file 1 time.

here configuration file each page.
